Sustainable City Charter

The charter is a business-led pledge which contains eight commitments for reducing carbon emissions from non-domestic buildings.

Westminster’s world-famous buildings help make London the incredibly exciting and vibrant place it is today. But non-domestic buildings also contribute 71% of the city’s greenhouse gas emissions. This contributes to climate change, impacting the quality of life of residents, workers, and visitors, and dictating how far buildings will continue to meet our needs into the future. 

The Sustainable City Charter is a free, voluntary, business-led pledge, supported by the Westminster Property Association and Westminster City Council. It encourages sustainable working practices across non-domestic buildings in Westminster.

It contains eight commitments for reducing carbon emissions from non-domestic buildings. These cover areas such as energy use, procurement, transport, waste and deliveries, and include committing to net zero buildings by 2040 or earlier.

Hear from one of our early signatories, the Royal Opera House, about how the Sustainable City Charter is helping them take steps to improve sustainability across their buildings. We are excited this iconic global institution has pledged to help us reach net zero by 2040.


And hear from one of our most recent signatories, The St Marylebone CE School, about their decision to join the charter. Kat Pugh, the school's headteacher, said:

St Marylebone students wear green and want to be green. They want to preserve and protect a world which is green, clean, healthy and sustainable. We are delighted to be part of the Sustainability City Charter to give credibility and momentum to our commitment to a more sustainable, climate-friendly life in our school community now and for years to come.

Upon signing up to the charter, your organisation will be granted access to an evolving toolkit of support and advice designed to help all kinds of organisations regardless of where you are on your sustainability journey. Working together to share knowledge and find solutions means we can collectively tackle the climate emergency.
